What's this, a water filter?

Deep in the voluminous aft compartment of my 1894 Baba 30 is an old looking thing that I guess is a fresh water filter. Anyone want to correct that? It looks neglected to me.

Sorry the pictures arent properly oriented. The close up is sideways and the overview is upside down.

Re: What's this, a water filter?

I haven't crawled around in the butt of my Baba yet so I can't really help but I just wanted to say nice boat!

Seems it would be some kind of cartridge filter if I had to guess. Looks like you could pop it open by removing those long bolts and the hoses to have a look.

Looks like it's connected to the thru hull valve via the Y valve.....guess that makes it a sea water filter...

I think it's this. Raw sea water strainer from GROCO

Re: What's this, a water filter?

I donít think itís a Groco Strainer. It looks a lot like a Groco SA series strainer but the cap is wrong and it doesnít seem to have a center rod. This is an important piece of hardware. It should be opened and cleaned fairly often.

Re: What's this, a water filter?

It's definitely an instake strainer for seawater cooling. Groco, Perko, Buck Algonquin or Wilcox Crittenden - no matter what brand the brass cylinder IS NOT original to the unit. It should be acyrlic to be able to see the strainer inside for debris/growth. All those brands will have a logo or name on the castings.

Re: What's this, a water filter?

It's a seawater strainer, likely for the engine. It sounds like you need to delve through your entire boat and learn what and where everything is! Have fun.

Re: What's this, a water filter?

Agreed. It's a sea strainer. The main cylinder is so murky and cloudy, it almost looks solid. Good idea to close the through hull valve, open the top of the cylinder, remove and clean the basket inside, and then put it all back together. Never forget to reopen the through hull valve. This procedure needs to be done periodically. It ensures plenty of decent-quality raw water is reaching your engine or generator.

You mentioned it looked like it had been neglected. It certainly needs to be cleaned inside. The basket should be emptied and hosed out and the inside of the cylinder could stand a decent scrubbing. If you're referring to the green patina and corrosion-like stuff, that's pretty normal and doesn't really harm anything but some, like moi, find it a bit annoying. Spread some SnoBowl toilet bowl cleaner on the green stuff and give it about five minutes. Scrub it off with a brush, rinse it with water, and let it dry. Should look much better after that. Once it's clean, I've heard some people even spray clear lacquer on the brass parts to keep them looking clean and green-free.

Re: What's this, a water filter?

Agreed - it is a seawater strainer. I have had one in Carina since the beginning. It is actually redundant if the intake thru-hull has a screen incorporated - I have never found anything inside the strainer besides sediment, which settles in the bottom. It's paid for and it's mounted so it stays...

I had assumed the cylinder was just dirty acrylic but you may be right that it is brass or bronze. Actually Groco did produce a strainer with a brass cylinder. They use stainless steel now. They also produce strainers with cast bronze single piece bodies, no separate cylinder.

Lol, so true. I have a lot to learn. Sailing rigs are the easy part. Engines are much more complicated :P. I'm in over my head, but starting to doggie paddle.

This makes sense. In hindsight it's obviously a raw water strainer and I hope can be restored to decent shape. I'll let ya'll know if I can ID the strainer - or if I can't. 35 year old Taiwanese boat that's been around a bit.

I think it would be crazy not to have one - that sediment is precisely the kind of thing I don't want in the heat exchanger.
